Abstract
The upward force exerted on an expansion cone (2), which is pulled up by a drill string (3) to expand a well tubular (1), is hydraulically enhanced by:—connecting a bottom plug (10) to a carrier body (11) below the expansion cone (2);—lowering the drill string (3), cone (2), carrier body (11), bottom plug (10) and unexpanded well tubular (1) assembly into a well;—inducing the drill string (3) to pull the expansion cone (2) through a lower edge (13) of the unexpanded well tubular (1) to expand said edge (13) and to subsequently pull the bottom plug (10) into sealing engagement with the expanded edge (13);—releasing the bottom plug (10) from the carrier body (11);—further pulling (F1) the expansion cone (10) through the well tubular (1) and simultaneously injecting fluid through the drill string (3) below the cone (2) to hydraulically increase (F2) the upward force (F=F1+F2) exerted on the expansion cone (2).
Description
- The invention relates to a method and system for enhancing the performance of a well tubular expansion assembly.
- A known well tubular expansion assembly and method are disclosed in International patent application WO2012104257.
- In this known method a well tubular is expanded by pulling an expansion cone therethrough by drill string pull.
- A disadvantage of the known method is that, in particular in deep and/or deviated wells, the drill string pull exerted to the cone may be limited and insufficient to expand an upper end of the tubular within a lower end of a previously installed well tubular.
- A further disadvantage of the known method is that it requires use of a top anchor that fixes an upper end of the expanded tubular within a previously installed tubular, which anchor may slip if a large upward force is exerted by the expansion cone to the expanding tubular.
- There is a need for and improved method and expandable well tubular wherein the upward force exerted on the expansion cone is hydraulically increased and wherein upward motion of an upper end of a partially expanded well tubular into a previously installed well tubular is inhibited such that forces on a top anchor are reduced.
- A known method for placing an expandable bottom plug at the bottom of an expandable well casing is expanded downhole is disclosed in International patent application WO2004/027200. This known method involves a two step installation and expansion process which requires intervention by an operator. There is a need for an improved bottom plug installation and subsequent expansion process that can be performed in one step without intervention of an operator.
- In accordance with the invention there is provided a method for enhancing the upward force on an expansion cone which is pulled up by a drill string to expand a well tubular, the method comprising:
- inserting the drill string through the unexpanded well tubular;
- connecting the expansion cone to a lower end of the drill string such that the expansion cone engages a lower edge of the tubular;
- connecting a bottom plug to a carrier body that is suspended below the expansion cone;
- lowering the drill string, cone, bottom plug and the unexpanded well tubular into a well until an upper end of the unexpanded well tubular is co-axially arranged within a lower end of a previously installed tubular;
- pulling the expansion cone by drill string pull through the lower edge of the unexpanded well tubular thereby expanding said lower edge;
- inducing the carrier body to pull the bottom plug into the expanded lower edge and to seal off said lower edge;
- inducing a release joint in the carrier body to release the bottom plug from the carrier body;
- further pulling the expansion cone by drill string pull through at least a substantial part of the lower tubular; and
- simultaneously injecting fluid through the interior of the drill string through a fluid discharge opening below the expansion cone into a space between the bottom plug and the expansion cone thereby hydraulically pushing the expansion cone through the lower tubular and increasing the upward force exerted to the expansion cone;
and wherein the expanded lower edge of the well tubular has an inwardly curved shape and the bottom plug comprises: - a sealing ring that is configured to sealingly engage said edge; and
- self-locking teeth that snap into the inner surface of said inwardly curved edge when the bottom plug is pulled into the lower edge.
- The fluid injection through the interior of the drill string may be continued when the expansion cone is pulled through the upper end of the lower tubular into the lower end of the previously installed upper tubular and the drill string pull and pressure of the fluid injected through the drill string may be adjusted on the basis of a monitored longitudinal movement of the expansion cone through the well tubular and a ration between downward hydraulic force exerted on the bottom plug and upward force exerted by the expansion cone on the tubular expanded thereby.
- An advantage of the method according to the invention over the method known from International patent application WO2004/027200 is that the bottom plug is positioned in the bottom of the expanded well tubular by letting it shoulder against the bottom end face of the tubular whereby the bottom plug is mechanically set by overpull to the expansion string. This enables the setting of the plug while the tubular string is being expanded, wherein the pipe expansion and shouldering, anchoring and sealing of the plug is performed in a single operational step without requiring intervention by an operator.
- After expansion of the well tubular the bottom plug may be drilled out and the expanded well tubular may then form another previously installed well tubular through which a subsequent well tubular is inserted and expanded in accordance with the method according to the invention, which process may repeated several times to generate a MOnoDiameter (MOD) well hydrocarbon fluid production well with a substantially constant internal diameter through which, after completion of the well, a larger flux of crude oil, natural gas and/or another hydrocarbon fluid may be produced than through conventional telescoping wells.
- In accordance with the invention there is further provided a tubular expansion assembly comprising
- a bottom plug connectable to a carrier body below the expansion cone;
- means for connecting the expansion cone to a lower end of a drill string and to pull the expansion cone by drill string pull into a lower edge of an unexpanded well tubular thereby expanding said lower edge;
- a release joint in the carrier body adapted to release the bottom plug from the carrier body when the bottom plug is pulled into the expanded lower edge of the lower tubular; and
- a fluid discharge opening near a lower end of the expansion cone into for injecting fluid through the drill string and expansion cone into a space between the bottom plug and the expansion cone thereby hydraulically pushing the expansion cone through the expanding well tubular and increasing the upward force exerted the expansion cone, and wherein the expanded lower edge of the well tubular has an inwardly curved shape and the bottom plug comprises:
- a sealing ring that is configured to sealingly engage said edge; and
- self-locking teeth that snap into the inner surface of said inwardly curved edge when the bottom plug is pulled into the lower edge.
- These and other features, embodiments and advantages of the method and expandable well tubular according to the invention are described in the accompanying claims, abstract and the following detailed description of non-limiting embodiments depicted in the accompanying drawings, in which description reference numerals are used which refer to corresponding reference numerals that are depicted in the drawings.
